Abstract(in English) | In this paper, the dependences of cross polarization on substrate dielectric constant are derived for a dual-polarized square patch antenna, and a novel design method is proposed to decrease cross polarization. The proposed one is to select the optimum dielectric constant. This method is based on the fact that the slope of the graph of dielectric constant versus cross polarization becomes reverse when the feed point is changed, and is effective for the planes tilted from the E-plane or H-plane. Also, considering effective dielectric constant, the above characteristics are validated both by the FDTD simulations and by experiments for a dual-polarized square patch antenna with a parasitic element. Moreover, in case of a patch antenna with a parasitic element, it is shown that the use of the optimum selection of dielectric constant, together with the use of the feed perturbation, is effective. |
